IMPROVEMENT IN CAR-couPLlNes.

Specification forming part of Letters Patent No. 129,896, dated July 30, 1872.

To all persons to whom these presents may come: Be it known that I, JOHN E. LEwIs, of South Boston, of the county of Suffolk and State of Massachusetts, have invented a new and useful Railroad v Oar-Coupling; and do hereby declare the same to be fully described in the following specication and represented in the accompanying drawing, of which- Figure 1 is a topview, Fig. 2 a side elevation, and Figs. 3 and 4 are longitudinal sections of one of my improved couplings,.one section being taken through the catch and the other l a, formed and Aarranged as shown. There is also within the chamber and aside of the slot a duplex latch or catch, B, formed as shown,

more, there is pivoted to the bunter an open or forked lever, D, provided with a rod, g, going across the opening h and under one prong of the T-piece. A spring, i, applied to the lever and the standard k, upon which it rests, serves to operate the lever, so as to keep the catch in engagement with another bunter, as well as to aid in eiiecting such engagement at the proper time. Another lever, E, pivoted to the bunter and jointed to the lever D, and provided with a lifter, E, serves, when the liiter is pulled upward, to move the lever E and cause its transverse rod, by means of the T-piece, to raise the latch B out of engagement with the fellow bunter. At the Sametime, as

the front prong of the T-piece of the latch of such fellow bunter will be over and across the rod of the open lever D, such latch of the fellow bunter will be raised out of engagement with the bunter carrying the lever D, the whole enabling the two railway carriages to be disengaged.

I claim- The combination of the duplexpronged T- piece O and the lever D, provided with the rod g and spring i, as set forth, with the latch B and the bunter chambered and provided with the catch-slot a, all being substantially as and arranged' in manner and to operate as specified.

JOHN E. LEWIS.
